Would Brokeback Mountain garnered as much praise had it been about a man and a woman?

I keep seeing comments from liberals that Brokeback Mountain isn't about homosexuality. "It's about love." For example:

Um, Brokeback Mountain ISN'T about being gay

The theme isn't homosexuality, but rather a universal one: not being able follow your heart can crush your soul. It just happened to have two male protagonists.

I could relate, and I'm straight... because dwickham is right, it's about love.

Movies win Oscars for being good movies, not for making political statements. Either Crash or Brokeback Mountain would have been worthy because they are both good films (and yes both have universal themes).

...

Why do you keep insisting that their gayness is so important?

What does it matter if it was a hetero or homosexual couple? Does it affect the quality of the love they share? Do gay people love differently or not as completely as straight people?

The ENTIRE POINT of the movie is that people fall in love, and when people who love each other are kept apart by forces beyond their control, everyone gets hurt. The POINT is that gay couples are NO DIFFERENT in their love than heterosexual couples. Why do you insist that they are?

So, okay, fine. It's not about homosexuality. "It's about love." Let's go with that for a moment. Take the plot of Brokeback Mountain and change one of the lead characters to a woman. Keep everything else as much the same as you can. Now, do you honestly - HONESTLY - think that liberals would've lauded over this movie as much as they have been? Would it have won the same awards? Would it have been nominated for the Best Picture Oscar? No. It wouldn't have. The ONLY reason it garnered as much attention was because it was about homosexuality.

Now, to be fair, most Christian conservatives wouldn't have come out so strongly against this movie, either, had it been about a man and a woman having a pre- and extramarital affair over the years. Some would likely have even gone to see it. Yeah, that's hypocritical and it's unfortunate. Brokeback Mountain was only one film out of hundreds each and every year that glorify sin. How many people who opposed Brokeback Mountain had no problem sending their kids off to see the latest sex-soaked comedy from Hollywood? Think, people! Think!
